Title: Lighting device
Inventor: TEJIMA YASUYUKI
IPC: F21V5/04
Filed: 1988-06-08
Abstract: PURPOSE:To obtain a lighting device which very effectively utilizes the illuminating light by setting the shape of the incidence end plane of individual micro- lenses constituting a fly eye lens to a nearly similar figure to the shape of a lit object. CONSTITUTION:A square drum lens A is used for a micro-lens 17a, the light emitted from a light source 100 enters an incidence plane A1 and goes out in a circle inscribed on the end face of a square at an outgoing plane A2. The end face image on an incidence plane A1 is formed on the outgoing side image forming face 101 of a condenser lens 18. This image (lighting region) 102 is a similar expanded image to the incidence light image of the incidence plane A1, when a translucent lit object (film) is placed at the region 102, the light quantity of the light source 100 is applied to the film with no waste. The circular image of the outgoing light of the outgoing plane A2 is formed on a projection optical system 12. When micro-lenses are collected to constitute a fly eye lens and incidence light images from individual micro-lenses are overlapped and formed, uniform lighting is obtained even if the light distribution characteristic and illuminance distribution of the light source have dispersion.

Title: Soldering of printed board and apparatus therefor
Inventor: MIYAMOTO EIJI
IPC: B23K1/08
Filed: 1989-06-02
Abstract: PURPOSE:To prevent a pattern short-circuit and to alleviate cleaning and inspecting steps by blowing air to the upper surface of a printed board while the lower face of the board is at least brought into contact with solder. CONSTITUTION:Air is blown to the upper face 11u of a printed board 11 while the lower face 11u of the board 11 is at least brought into contact with solder 3 in a solder tank 2. Accordingly, when the lower face 11d of the board 11 is brought into contact with the solder 3, the air W is brought into contact with the upper face 11u thereby to temporarily cool the upper face 11u. As a result, the solder 3 on the upper face 11u is rapidly solidified, thereby suppressing generation of a solder ball. Thus, a pattern short-circuit is prevented, and cleaning and inspecting steps are alleviated.

Title: Manufacture of higher cupric acid salt complex
Inventor: AASAA RII KIYANBERU
IPC: C07F1/08
Filed: 1988-06-08
Abstract: This invention encompasses a process for preparing higher order cuprate complexes which contain a carbanion for the formation of carbon to carbon bonds in reactions such as 1,4-conjugate addition. The complex is formed by reacting a first cuprate complex with a stannane such that the carbanion to be used to form carbon to carbon bonds is transferred from the stannane to the first cuprate complex to form a different higher order cuprate complex. This process permits the in situ preparation of a higher order cuprate complex having the carbanion desired to be used in a synthetic reaction. Higher order cuprate complexes prepared by this process are particularly useful for the efficient preparation of pharmacologically active prostaglandins.

Title: Binder for magnetic recording body and magnetic recording body
Inventor: OKUTO MASAZUMI
IPC: C09D5/23
Filed: 1995-06-08
Abstract: PURPOSE: To improve the dispersibility of polyvinyl acetal resin to a styrene- acrylic acid copolymer by grafting the polyvinyl acetal resin with a copolymer of a styrene monomer with (meth)acrylic ester. CONSTITUTION: This binder is based on a graft polymer consisting of 0.5-30wt.% polyvinyl acetal resin having a polymn. degree of 200-4,000 and 70-99.5wt.% copolymer of a styrene monomer with (meth)acrylic ester. This binder has superior magnetic powder dispersing ability and forms a heat resistant magnetic coating film excellent in wear resistance. The reason for the properties of the binder is that the dispersibility of the polyvinyl acetal resin to a styreneacrylic acid copolymer is extremely improved because the styrene monomer is copolymerized with the (meth)acrylic ester by soln. polymn. in the presence of the polyvinyl acetal resin.

Filed: 1979-11-01
Abstract: PURPOSE:To keep an operating point of a quartz oscillation circuit, even if the voltage of a cell is in variation, by driving the quartz oscillation circuit with a constant current circuit of optimum design. CONSTITUTION:The voltage at the connection point between a resistor 10 and an MOSFET 11 is almost at a constant voltage to the voltage variance of a cell 8, since the voltage-current characteristics of the MOSFET 11 are shown as a quadratic equation. The gate voltage at an MOSFET 9 is also at a constant voltage against the voltaage variation of the cell 8, and when an FET 9 operates at a saturation area (pentode area), the current flowing to the FET 9 is constant. Accordingly, even if the voltage of the cell decreases near 1.0V, the operating point of MOSFETs 1 and 2 is unchanged for stable operation.
